NAME VDIF Microservice Model
GENERAL DESCRIPTION 
This interface does not call FileMan Database Server
(DBS) APIs directly. All data operations are performed through a service
managed object class. Read requests are satisfied by the microservice's query
handlers, which retrieve and materialize Item Master objects from the
service's data access layer and return API; no direct consumer access to
underlying FileMan files occurs. Write requests (create/update) are processed
by command handlers that apply validated business rules in the service layer,
execute persistence through service side adapters. Concurrency controls,
validation, and referential integrity are enforced within the service. This
pattern isolates consumers from FileMan, centralizes business rules, and
ensures consistent updates.


The proposed integration uses an object class model for Item Master data.
Consumers interact only with the service's API endpoints. The service
encapsulates all persistence and validation logic.

Mechanism: Query handlers load domain objects via the service's data access
layer.

Behavior: Read operations do not traverse FileMan from the consumer context.
The service may employ caching and projections to optimize reads while
preserving consistency.

Result: Consumers receive fully materialized Item Master objects shaped by the
object class.
